My Spring Boot Restservice App is running just fine in normal Spring App Context. But when I try to run it on Google App Engine the following Exception is thrown:

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.transaction.PlatformTransactionManager]: Factory method 'transactionManager' threw exception; nested exception is java.lang.ClassCastException: org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean$$EnhancerBySpringCGLIB$$1c05fbf5 cannot be cast to javax.persistence.EntityManagerFactory

here is the stacktrace of my exception:

I was having the same problem today converting a part of a Spring application to a Spring Boot application. The problem was that Spring kept loading a default entityManagerFactory bean.

In order to use my entityManagerFactory bean I had to return the instance of LocalContainerEntityManagerFactoryBean directly, instead of returning LocalContainerEntityManagerFactoryBean's getObject():

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {

  HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
  vendorAdapter.setGenerateDdl(true);
  vendorAdapter.setShowSql(true);
  vendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQLDialect");

  LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
  factory.setJpaVendorAdapter(vendorAdapter);
  factory.setJpaDialect(new HibernateJpaDialect());
  factory.setPackagesToScan("com.pekam");
  factory.setDataSource(MyDataSource());
  factory.afterPropertiesSet();


  return factory;
}

and then in the configuration of the transactionManager bean call entityManagerFactory().getObject():

@Bean
public PlatformTransactionManager transactionManager() {

  JpaTransactionManager txManager = new JpaTransactionManager();
  txManager.setEntityManagerFactory(entityManagerFactory().getObject());
  return txManager;
}
